PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power source requirements speci
fi
ed on the
product nameplate.
2. Power
switch
Ensure that the switch is in the OFF position. If the
plug is connected to a receptacle while the switch is
in the ON position, the power tool will start operating
immediately and can cause serious injury.
3. Extension
cord
When the work area is far away from the power source,
use an extension cord of su
ffi
cient thickness and rated
capacity. The extension cord should be kept as short
as practicable.
WARNING
Damaged cord must be
replaced or repaired.
4. Check the receptacle
If the receptacle only loosely accepts the plug, the
receptacle must be repaired. Contact a licensed
electrician to make appropriate repairs.
If such a fautly receptacle is used, it may cause
overheating, resulting in a serious hazard.
5. Checking and installing the diamond wheel
Check the diamond wheel is a speci
fi
ed one and is not
cracked, broken or bent. Check the diamond wheel is
installed securely. For installation, refer to “Installing/
removing diamond wheel”.
6. Fitting and adjusting the dust collection cover
(Fig. 2)
The dust collection cover is a protective device to
prevent injury should the diamond wheel shatter during
operation. Ensure that the cover is properly
fi
tted and
fastened before commencing cutting operation.
By slightly loosening the setting screw, the dust
collection cover can be turned and set at any desired
angle for maximum operational e
ff
ectiveness. Ensure
that the setting screw is thoroughly tightened after
adjusting the dust collection cover.

CAUTION
●
Leaving the wing nut loosened may result in injury.
Securely tighten the wing nut after adjusting the
cutting depth.
●
When the cutting depth exceeds 13/64” (5mm),
concrete, and so on must be cut in two steps.
Never try to cut in one step; otherwise, the motor
is liable to be overloaded and damaged may result.
Also, cutting e
ffi
ciently will be lower in such an
instance.
